In distributed solar generation systems, every generation unit is enabled to perform its main functions at the individual photovoltaic (PV) panel level rather than on a string or array of photovoltaic modules. Two implementations are possible using either solar micro-inverters – fed by a single panel and directly connected to the AC grid – or by means of power optimizers – fed by a single panel in a string that performs the Maximum Peak Power Tracking (MPPT) with its output connected to feed a single inverter.

The power rating for each unit is typically between 50 and 400 W and a data logger and internet gateway collects data from all the panels and inverters and sends this information to a local or remote monitoring and control access point with efficiency and reliability being key to a successful design.

Semiconductor technologies and products are key enablers to competitive designs and we have a range of products and solutions including silicon-carbide (SiC) MOSFETs and diodes, HV super-junction MOSFETs and IGBTs, application-specific analog products (ASSP) – including and IGBT and MOSFET gate drivers – and STM32 microcontrollers that can help developers meet these challenges.
